Special Issue Information

Dear Colleagues,

Climate change is growing to be a bigger threat to mankind. Rising temperature, along with higher sea level, would someday bring disasters. To meet this crisis, the goal of carbon peak and neutrality has been proposed aiming at reducing the emission of carbon dioxide. This goal can only be achieved with joint efforts of novel technologies from different areas. We need the technologies to reduce the emitted carbon dioxide, by capture, storage, conversion and utilization. As a large amount of carbon dioxide comes from the combustion of fossil fuels, the renovation of energy system could change the energy supply mode and reduce the gas emission: spread the use of renewable energies, make systems more efficient and take the energy storage strategy as much as possible. Moreover, green buildings and green industrial processes are also important for curbing the carbon dioxide emission. Those technologies are the hope for a low carbon development, and the related scientific topics will be hot spots in the following years. This issue would like present the most innovative and potential ones for readers.

We solicit contributions on topics including but not limited to:

  • Novel technology in carbon dioxide capture and storage;
  • Novel technology in carbon dioxide conversion and utilization;
  • Innovation of high efficiency energy systems;
  • Innovation, exploration and application of renewable energies;
  • Novel energy storage technology in new energy systems;
  • Novel green building technologies, green HVAC systems;
  • Novel green industrial processes;

The demand for sustainable economic growth highlights the trade off between environmental and economic targets. From the perspective of economic growth target (EGT) management and green innovation (GI) practice, in this study, we constructed dynamic panel, spatial Dubin, quantile, and threshold models to measure the impact of EGT on GI using the panel data of 284 prefecture cities in China from 2006 to 2018. The results show that EGT has a negative impact on GI, which is characterized by dynamic, superposition, spatial, and nonlinear effects; there is remarkable heterogeneity in different regions, development stages, and urban characteristics, and the empirical conclusion is still credible under many robustness tests. We also studied the heterogeneous impact of economic growth targets with different characteristics on green innovation. This study puts forward policy implications from two perspectives: optimizing top-level design and maximizing the trade off in multi-objective accountability. Full article

As a theory in ancient China, Feng Shui is used in terrain exploring to find ideal living environments. In this study, 62 traditional villages documented on China’s and Jiangxi’s protection lists in Jinxi County, Jiangxi Province were divided into four categories according to their landscape patterns and were simulated by CFD (computational fluid dynamics) with PHOENICS and quantitatively analyzed based on their wind and thermal environments. The results showed that hills greatly improve the wind environment of villages when they are in the windward direction. Concerning thermal environments, water and vegetation effectively reduced the summer temperatures in villages, while hills kept villages warm in winter. This paper verified the positive effect of elements such as mountains, water and forests on the improvement of wind and thermal environments of villages and the rationality of the site election principle of Bei Shan Mian Shui, also known as back mountain facing water, which is upheld by Feng Shui. This paper explored the philosophy of traditional village location selection, demonstrating the ecological wisdom of ancient Chinese people in creating a good living environment, and provides a new direction for current sustainable development planning.

Renewable energy is a key technology for achieving carbon-free energy transitions, and solar power systems are one of the most reliable resources for achieving this. Solar power systems have a simple structure and are inexpensive. However, depending on the input irradiance, the existing maximum output control algorithm (P&O) has disadvantages due to its slow transient response and steady-state vibration. Therefore, in this paper, we propose a maximum output control algorithm based on a deep learning algorithm that can predict the input irradiance. This can achieve a quick transient response and steady-state stability. The proposed method predicts the irradiance based on the output voltage/current and power of the photovoltaic (PV) system and calculates the duty ratio that can accurately follow the maximum output point according to the irradiance. The deep learning model applied in this study was trained based on the experimental results using a 100 W PV panel, and the performance of the proposed algorithm was verified by comparing its performance with that of the conventional algorithm under various input irradiance conditions. The proposed algorithm exhibits a maximum efficiency increase of 11.24% under the same input conditions as those of the existing algorithms. Full article
